Dynasend
Dynasend centrally designs and manages standardized email signatures for Microsoft 365 users and devices. Administrators deploy and update signatures across a tenant through its O365 add-in, without requiring end-user desktop installs. It can create a design or convert an existing one, with variants for new messages, replies, and streamlined messages. Entra ID (Azure AD) sync aligns signature fields with directory attributes, while SCIM provisioning supports user lifecycle management. Multiple templates and unlimited user data fields can serve different brands and divisions. Campaigns can schedule banners, notes, relocation messages, and role-based groups; the platform also offers feedback surveys and digital business cards for iOS and Android. Dynasend says signatures render in Outlook at compose time, data is encrypted in transit and at rest, and it does not access email content or stamp messages in transit. Standard costs $50 a month for up to 50 signatures; above that, monthly per-active-signature pricing varies by volume from 1.00 USD (51–100) to 0.20 USD (18,001+). A 90-day free trial is available.
